Understand This Product — TechCureIndia

What it does

This is a 240mm closed-loop liquid cooler that transfers heat from the CPU to a radiator via a pump-driven coolant loop, cooled by two case-mounted fans, with an added small fan to blow air over nearby VRM heatsinks.

What the key specifications mean

• Radiator Size (240): Fits cases with 240mm radiator mounting; two 120mm fans provide the airflow
• Pump Speed (800–2800 rpm, PWM): Speed scales with PWM signal, allowing quieter operation at idle and higher cooling at load
• Cold Plate (Copper, Micro Skived Fins): Efficient heat transfer from the CPU surface into the coolant
• TIM (MX-6, 0.8 g): Thermal paste is pre-applied, so no separate purchase is needed for first installation
• Tube Length (450 mm) & Diameter: Long enough for most ATX case layouts; flexible outer/inner diameter aids bend radius
• Radiator Fan Airflow/Static Pressure (77 cfm / 6.9 mmH2O): Indicates the fans' ability to push air through the radiator fins for heat dissipation
• VRM Fan (400–2500 rpm, PWM): Extra airflow directed at motherboard VRM area, useful for boards with passive VRM heatsinks
• Compatibility (Intel 115X/1200/1700/1851, AMD AM4/AM5): Confirms which CPU sockets the mounting hardware supports
• Weight (1675 g): Useful to check case support and radiator mounting strength
• Operating Ambient Temperature (0—40 °C): Defines the safe ambient range for operation

Practical benefits

• Covers a broad range of current and recent CPU sockets
• PWM pump and fans allow noise/performance tuning via motherboard control
• Pre-applied thermal paste simplifies installation
• Additional VRM fan supports sustained performance on boards with less VRM cooling
• 6-year warranty supports long-term use

Who it suits

• Builders assembling high-performance Intel or AMD desktop systems
• Users running CPUs with higher sustained thermal output
• PC builds where consistent cooling and quiet-to-performance scaling is wanted

Compatibility and installation

• Must match one of the listed Intel sockets (115X, 1200, 1700, 1851) or AMD sockets (AM4, AM5)
• Case must support a 240mm radiator with the given radiator dimensions
• Requires radiator mounting space of 277 x 120 x 38 mm
• Pump operates on 12V DC, 0.35A; VRM fan on 12V DC, 0.05A; radiator fans on 12V DC, 0.33A each
• Fans use 4-Pin PWM fan connectors
• 450 mm tube length should be checked against case routing path from CPU socket to radiator mount

Important limitations

• Only compatible with the specific sockets listed; other sockets are not supported
• Operating range limited to 0—40 °C ambient

Package contents

• MX-6 thermal compound pre-applied (0.8 g)

Buy separately:

• Case with 240mm radiator mounting support, if not already available
• Motherboard with compatible socket, if not already owned

Check before you buy

• Confirm your CPU socket matches the supported list
• Confirm case clearance for 277 x 120 x 38 mm radiator and fan stack
• Check available fan headers/PWM connectors on the motherboard for pump, radiator fans, and VRM fan
